    Hi, D Richard Felker III!

Sometime (on Monday, April 26 at 11:24) I've received something...

    Of course, it does. Of course, only if muxing stream has that frame
already. Muxer does nothing weird but compile input streams into packets
and give out. As each muxer will do, of course. If you give muxer just
zero-length packet without header then what muxer will assume? Is it a
predictional or bidirectional frame, or even a GOP? What PTS it has?
Muxer should get at least a stream packet header even for frame with zero
data. It's not a problem of muxer but one of codec. :)

    With best wishes.
    Andriy.
